Maintenance
Cooling Coils: Cleaning and Replacement Procedures
1. Shut down the dryer, tag out and lock out the controls if
necessary.
2. Shut the water off to the cooling coil.
3. Remove the four 10-32 bolts.
4. Gently slide the cooling coil out.
5. Visually inspect the coil for leaks, dirt, and any sign of
contaminants.
6. Blow the dust out, or if the coil is covered with plasticizer,
steam clean it.
7. Place the coil back in its housing. Make sure the gasket is
undamaged; replace if necessary.
8. Inset the four 10-32 bolts back in place.
9. Turn the water to the cooling coil back on.

Filters: Recommendations for Cleaning and Replacing
1. Turn off and/or lock out electrical power to the dryer.
2. Loosen the clamp, and remove the dust can.
3. Remove the thumb nut, on the center retaining rod, to remove the
filter cartridge.
4. Pull the filter cartridge out.
Vacuuming
• Try vacuum-cleaning a soiled filter first. Vacuuming removes most
large particles and surface contaminants, and may suffice for the first
time you clean a filter.
• Use a commercial-duty (recommended) or household vacuum
cleaner. Vacuum the filter from the air intake (dirty) side only.
Cleaning with Compressed Air
1. Blow clean, dry, compressed air up and down the pleats, blowing out
the filter from the inside out.
2. Remove loose dirt from the filter with compressed air or vacuum from
the outside.
3. Inspect the filter element. Briefly hold a light bulb behind the element
and look for any fatigued paper or residual dirt. Inspect for holes and
tears by looking though the filter toward a bright light. Check for
damaged gaskets or dented metal parts.
Note: Do not re-use a damaged filter!
